The utility model discloses a disc pelletizer disk body structure has been simplified, and the connection between limit dish and the middle part disk body is more firm, has improved the circularity of disk body structure.

Description

Disc body structure of disc pelletizer

Technical Field

The utility model relates to a balling disc field particularly, relates to a balling disc body structure.

Background

The disc pelletizer is used for manufacturing green pellets in a pellet production process in the steel industry, and mainly comprises a disc body, a transmission system, a slewing bearing and the like; during production, the disc pelletizer needs to work continuously and the working environment is severe, so that the disc assembly and the main parts of the disc pelletizer are required to be reasonable in structure, simple and reliable and convenient to maintain.

The disc body of the traditional disc pelletizer is formed by assembling 6 identical discrete parts, the parts are connected through a common connecting bolt, and the side disc and the central disc body of the disc pelletizer are connected through a connecting plate through the common connecting bolt; in the actual operation process, due to the dispersed structure of the disc body, the connection bolt is low in connection firmness, so that the connection bolt is loosened when the disc body operates, the roundness of the disc body is seriously influenced, and the service life of disc assembly of the disc pelletizer is greatly reduced.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a balling disc disk body structure aims at preventing that the disk body is not hard up, guarantees the circularity of disk body assembly, prolongs the life of disk body assembly.

In order to solve the above problem, the utility model adopts the following technical scheme:

the utility model provides a balling disc disk body structure, is including setting up limit dish and central disk body with one heart, and the limit dish is split type structure and includes the same arc disk body of three structure, and butt joint department between the adjacent arc disk body is through hinge bolted connection, and the inner edge of arc disk body and the outer fringe of central disk body are respectively for the cambered surface structure of mutually supporting and through hinge bolted connection as an organic whole.

Compared with the prior art, the utility model discloses an installation method's advantage lies in:

the side plate is composed of three arc-shaped plate bodies, so that the side plate structure is simplified, and the stability of the whole side plate structure is enhanced; the side plate and the central plate body are connected through a cambered surface structure, so that the side plate and the central plate body are tightly embraced and connected more stably; through hinge bolted connection between the arc disk body and between limit dish and the central disk body, the hinge bolt can play the positioning action, can play the connection effect again, makes the disk body do not have not hard up phenomenon at the in-process of actual operation, and the disk body operates more steadily firmly, has prolonged the life of disk body greatly.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments. It is to be understood that the following description is only for purposes of clearly illustrating the present invention and is not to be taken in a limiting sense.

Fig. 1 and 2 show a disk body structure in the prior art, a side disk 1 and a central disk body 3 are connected into a whole through a connecting plate 5, wherein the connecting plate 5 extends into a groove formed on the outer side of the central disk body 3, the connecting bolt 2 is connected with the central disk body 3, and the connecting bolt 2 is connected with a bottom plate 4 of the side disk 1. Because the structure is connected through the connecting bolt 2, the firmness degree is low, and the looseness is easy to occur in the operation process.

Referring to fig. 3 to 5, a disk body structure of a disk pelletizer is shown, which comprises a side disk 1 and a central disk body 3 arranged inside the side disk, and the side disk 1 is provided with a bottom plate 4. The side plate 1 and the central plate body 3 are concentrically arranged, the side plate 1 is of an annular split structure, and the central plate body 3 is of a circular structure. The side plate 1 is composed of three arc plate bodies with the same structure, each arc plate body is of a 120-degree fan-shaped structure, the inner edge of the arc plate body (shown in figure 2) of the side plate 1 and the outer edge of the central plate body 3 are of arc surface structures which are matched with each other respectively, the arc surface structures are attached to each other more tightly, the roundness of the plate body is guaranteed, the corresponding positions of the arc surface structures are provided with hinged holes, and the hinged bolts 6 are connected in the hinged holes. In addition, the butt joint of the arc-shaped disc bodies is provided with a hinged hole, and the arc-shaped disc bodies are connected through hinged bolts 6. Because the front end of the hinged bolt 6 is provided with the thread for connection, and the polish rod without the thread at the rear end has positioning effect, the connection firmness of the tray body is enhanced.

The utility model discloses a disk body structure has obtained simplifying, adopts the hinge bolt to play the positioning action, can play the connection effect again, makes the disk body do not have not hard up phenomenon at actual moving in-process, and cambered surface structural connection has realized closely laminating of limit dish and central disk body simultaneously, has kept the circularity and the stability of disk body, has prolonged the life of disk body greatly.

The above description is only the preferred embodiment of the present invention. Various modifications and equivalent changes may be made by those skilled in the art without departing from the spirit and scope of the present invention, and such modifications and changes are intended to be included within the scope of the present invention.

Claims

1. The utility model provides a balling disc disk body structure, is equipped with bottom plate, its characterized in that including setting up limit dish and central disk body with one heart on the limit dish: the side plates are of a split structure and comprise three arc-shaped plate bodies with the same structure, the butt joints between the adjacent arc-shaped plate bodies are connected through hinge bolts, and the inner edges of the arc-shaped plate bodies and the outer edge of the central plate body are of arc-shaped structures matched with each other and are connected into a whole through the hinge bolts.
